just installed 1zz throttle body
Disconnected the battery. Took out the original tb. Applied gasket maker on 1zz tb but i let sit for only a few min. Put the new tb in but realized the coolant hose didnt fit so i bypassed it with a brass pipe that i got from lowes for 3 bux. Installation took about 45 mins i think. Reconnected the battery and started the car. No check engine light but At first the car sounded as if it was dying for 5 seconds but after that it stayed at a 4k rev then dropped down to 2k within 10 seconds. I had the car on for 15 mins. As i was driving i didnt notice much of a change when i accelerated moderately from 0 to 6(i guess i expected too much from a throttlebody) but as soon as i floored it, the rpm shot up to 6.5k rpm easily. When i leave have the car in neutral the car is rev hunting from 1k-3k for liken 5 seconds( i have an automatic)I just hope nothing bad will happen since i bypassed the coolant and i only waited a few minutes to install the tb after i applied the gasket maker. Overall, this mod was okay lol. Next mod: mi crank pulley.
Btw i didnt adjust the idle screw yet so let me know what you guys think.
